I had dark blonde hair that and I used to have the t-section highlighted 2-3 times a year, but for the last couple of years I haven't needed to - I reached a sweet spot where it was going grey but the grey looked ash blonde.
However, now it is clearly grey, and I want to start adding colour back before it's too late and looks obvious. Can anyone recommend any home dyes - basically dark blonde low lights? I'm happy to buy a selection and do strand tests. I'm going to talk to my hairdresser but in a few months we are moving to a country where the cost of living is astronomical and I'm not one to spend £200 a pop on my hair....
